SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 249,890, dated November 22, 1881.

Application tiled April 16, 188i. (Model.)

To all lwhom 'it may concern Be it known that I, LEROY BROWN, of Waitsburg, in the county of Walla Walla, and rllerritory of Washington, have invented a new and useful Improvement in sulky-Plows, of which the following is a specification. v

Figure l is a plan view of my improvement. Fig. 2 is a side elevation of the same, the near wheel being removed. Fig. 3 is a plan view of the adjacent ends of the bars that support the tongue. Fig. et is a front elevation and a plan view of the plate to which the tongue is pivoted. Fig. 5 is a front elevation of the up per part of the lever and its attachments forcontrolling the tongue. Fig. 6 is a bottom view of the plow. Fig. 7 is a sectional side elevation of the plow. Fig. Sis an elevation ofthe land-side part of the rotary-colter standard. Fig. 9 is au elevation of the plowed-land part of the rotary-colter standard. Fig. 10 is a front elevation of the rotary colter and its standard. Fig. 1l is an end elevation of the rotary-colter hub.

The object ofthis invention is to improve the construction of the sulky-plows for which Letters PatentNos. 211,696 and 226,705 were granted to me January 2S, 1879, and April 20,1880, respectively, in such a manner that they will be more substantial, and can be more conveniently guided, controlled, and adjusted.

A are the wheels, and B is the axle, of the carriage. To the axle B, at the inner side of the off wheel A, is secured a casting or coupling-block, C, to the rabbeted outer side of the rear end of which is secured by bolts or rivets the lower end of a bar, D. The bar D extends upward vertically to about the level of the top of the wheel A, and is then bent forward at right angles. At the forward side of the wheel A the bar D is bent at right angles inward, forward, and again inward, forming a recess or offset.

To the lower side of the coupling-block (lis Vsecured by bolts or rivets the rear part of a bar, E, which extends forward, and at the forward side of the wheel A is bent upward at right angles, so that its upper end will overlap the bar D at its first inward bend.

To the axle B, at its inner side of the near wheel A, is secured a casting orcoupling-block,

ward at right angles, so that its end will overlap the body 'of the bar D at its first inward ,I

bend. The ends of the bars E G are secured to the bar D by bolts or rivets, and the end ofthe har D is secured to the bar G by bolts or rivets, as shown in Fig. 3, thus forming a rlu support for the tongue H.

Upon the box or frame formed by the end parts ot` the bars D E Gr is placed a plate, I, upon the ends of which are formed lugs J to rest against the sides of the bent end parts of the bars D G. The lugs J project below the lower edges of the bars D G, and are perfo rated to receive the bolt or pin K, by which the plate I is secured in place, and which rests in notches in the lower edges of the said bars D G. The tongue H rests upon the plate I, and is pivoted to it by a vertical bolt, L, passing through the said plate and tongue, as shown in Figs. l and 2. The rear part of the tongue H passes back nearly to the forward bend ot' the bar D, and to the lower side ot' its said rear part is secured, hy bolts or rivets, a flat bar, M, which rests upon the horizontal part ot' the bar D, and its rear end passes through and projects beyond a horizontal guide or igeeper, N, attached to the bar D at its angle. The keeper N holds the rear end of the tongue H down to its place and limits the lateral movements of the said tongue H. The rear end of the bar E projects a little beyond the rear end of the coupling-block C, and has a pivot formed upon it to receive the lower end of the lever O, which passes up1 across the rear edge of the keeper N, and is held against the said keeper by a spring, P, attached to the IOC can be adjusted to regulate the line of draft and cause the plow to take or leave land, as desired. The forward end of the pivoted catch Q is beveled, so that it will engage with the end of the tongue-bar M automatically, andis held down upon the said tongue-bar by a spring, R, attached to the lever O, or to an arm, S, or other' support attached to the said lever. The outer end, T, of the arm S is bent downward, or has a downwardly -projecting arm attached to it, to serve as a stop to prevent the engaging end of the catch Q from dropping down so low that it will not engage with the end ot' the tongue-bar M when the said end is swung against it.

To the upper side of the rear edge of the keeper N is attached, or upon it is formed, a catch-bar, U, with the teeth of which engages the lower end ot' the spring-pawl V. With this construction the lever O and the tongue H M can be adjusted to cause the plow to take or leave land, as required, and the tongue can be left free to vibrate in turning. rlhe rear end of the bar Gr projects in the rear of the coupling-block F, and to it is hinged the end ot1 a bar, Z, which is bent laterally, passes across the rear end of the machine at a rearward inclination, passes around the rear side' of the off wheel, passes forward parallel with the said wheel, and is bent inward around the forward part of the wheel.

The forward end of the bar Z is pivoted to the crank-arm of the bent lever a. The middle part or body otv the lever a is placed parallel with the axle B, and works in bearings attached to the horizontal parts ofthe bars E G. The inner arm ofthe bent lever a projects inward and upward into such a position that it can be conveniently reached and operated by the plowman from his seat. The bent lever a is secured by a ratchet-plate, b, and a spring-pawl.

To the rear side ofthe lower part ot' the moldboard j are attached, or upon it are formed, lugs p, which lugs p may be a projecting end ot the lugl and arm m or frog ot' the plow. The lugs p interlock with the lugs q formed upon the rear part of the share n, so as" to hold the rear edge of the share n against the forward edge of the mold-board j and hold the said share from lateral movement.

The share n is held from forward movement by the rod r, the forward end ofwhich is hooked into a holein the rear end of the inner lug, q, or in a separate lug attached tothe said share. The rear end ot' the rod r passes through a lug, s, secured to the rear upper part of the bar fc', and has a nut screwed upon the said rear end. With this construction the share n will be drawn tightly into place by tightening the nut of the rod r, and can be quickly detached by loosening the said nut.

t is the rotary colter, the hub u of which is made long to give it a long bearing upon its axle, preventing a rapid wear, and causing it to wear true. The hub u is provided with an axle-box, e, of anti-friction metal, to cause it to work easier and wear longer. The axle of the rotary colter t is attached to the lower ends of the two bals w, that form the standard. The bars fw pass up upon the opposite sides of the colterv t, and at a point a little above the top ot' the said colter have inward oifsets formed upon them, so that their upper parts may rest against each other. The upper part of the standard w is secured to the plow-beam g and bar Z by a clamp, which may be one of the clamps that secure the beam g to the bar Z, or a separate clamp, as may be desired or convenient. The upper parts of the bars 'w are secured to each other by a bolt, fr, which passes through a hole in one of the said bals and a slot in the other bar, as shown in Figs. 8, 9, and l0, and has a nut screwed upon its forward end. By this construction, by loosening the bolt .r the bars w can be moved upon each other to adjust the colter t exactly in the hne ot' draft and equalize the bearing on its axle, so that it will work easy and true and without any undue strain upon its axle or standard.

y is the drivers seat, which is attached to the upper end of the standard z. The lower end of the standard z is secured by a bolt, 1, toy the rear of the coupling-block 2, attached to the axle B.

Havingthus described my invention, I claim as new and desire to secure by Letters Patentl. In a sulky-plow, the combination, with the bent bar l), the tongue H, and the lever O, ofthe keeper N, the spring-catch Q R, and the ratchet and pawl U V, substantially as herein shown and described, whereby the tongue can be readily adjusted, securely held, and conveniently released, as set forth.

2. In a sulky-plow, the combination, with the rotary colter tand the plow-beam g, of the standard formed ot' two bars, w, secured to each other by a bolt, x, passing through a hole in the one bar and a slot in the other, substantially as herein shown and described, whereby the said colter can be readily adjusted into line with the draft, as set forth.
